FIRE-EXTINGUISHER.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed February 19. 1907. Serial No. 358.237.

T o all whom it Imay concern:

Be it known that I, HENRY SIEBEN, a citizen of the United States, residing at Kansas City, in thev county of Jackson and State of Missouri, have invented certain new and useful Improvements in Fire-Extinguishers, of which the following is a specification.

This 'invention relates to fire extinguishers, and more especially to an extinguisher of that type embracing a bucket of water, a pump connected therewith, and a chemicalbasket above the water and adapted to dump its contents therein, and my object is to produce a device of the character outlined which will operate efficiently and can be manufactured and sold cheaply.

To this end the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed and in order that it may be fully understood reference is to be had to the accompanying` drawing, in which,

Figure 1, is a horizontal section on the line I-I of Fig. 2. Fig. 2 is a substantially vertical section taken on the line II-II of Fig. 1, with the hose attached to the nozzle of the pump.

In the said drawing, 1 indicates a bucket of any suitable or preferred type adapted to be provided with a handle, not shown, 2 a lug projecting upward from the bottom of the same near one margin, and 3 is a finemesh screen wall or shield surrounding said lug for a purpose hereinafter explained.

4 indicates a cover for the bucket provided with an opening 5 and with an opening 6 through which extends a pump 7, the lower end of the pump being disposed within wall or shield 3 and secured in any suitable manner on lug 2. At its upper end the pump has a handle 8, and the discharge pipe or nozzle is provided with hose connection 9. The pump is of the type shown or of any other suitable or preferred type, its yieldingly seated valve 10 being adapted to open as the handle is pulled upward and close as such movement is reversed. The valve `11 closes as the handle is pulled upward and opens as it is pushed downward in order that waterdrawn into the pump by the upward movement of the handle shall be discharged therethrough on its downward movement. The special construction of the pump is of no particular importance as to such construction I make no claim. y

Hinged as at 1.2 to the cover at the rear edge of opening 5, is a foraminous quadrilateral cage 13, and projecting from the same are side flanges 14 and end flanges 15 to overlap and rest upon the cover at the side and end margins respectively, of its opening 5, the rear-end flange being connected by hinge 12 to the cover. The front-end flange is adapted to be overlapped by a turn-button or catch 16 pivoted to the cover and adapted to be turned to one side, as indicated by the arrow, Fig. 1, when it is desired to raise the cage. A basket surrounded by said cage consists of a closed top 17, downwardly converging walls 18, a bottom 19, hinged to the lower part of the rear end-wall 18 and a partition 20, the bottom being provided with a spring-catch 21 to snap onto a projection 22 of a bracket 23 secured to the front end-wall of the basket and forming a guide for the push rod 24 extending also through the top 17 and provided with a head 25 at its upper end and a spring 26 between the top and said head; said spring normally supporting the rod just above the hinged bottom 19 and so close to the same that a downward pressure on the head shall result in disconnecting the spring-catch from the lug 22 and permit the hinged bottom to swing down to a vertical position and discharge the contents ofthe chambers of the basket into the water. The chambers contain substances which chemically coact when immersed in the water to produce a compound which is far superior to water alone in its fire extinguishing effects, this compound being pumped by the person in control and directed through the use of. the hose to the point desired. The precipitation of the chemicals into the water is followed by their quick dissolution and the screen wall or shields is intended to prevent any particles of the chemical substance from obtaining access to the valves of the pump and interfering with their proper operation.

When it is desired to recharge the basket with chemicals, the catch or button 16 is thrown to one side and the foraminous basket-carrying 'cage is grasped and swung back on hinge 12 until the bottom of the basket is uppermost. The chambers are then charged as explained and the bottom is closed and locked in such position by the catch 21 and lug 22. The foraminous cage is then swung back to the position shown in the drawings and is relocked in such position by the button, the device as thus arranged being immediately ready for service when needed.

"Y It will be observed that the provision of the foraminous cage surrounding and spaced from the basket and in communication with the interior of the bucket permits of the circulation of air around the basket'and thus protects the contents of the latter from being dampened by the vapor arising through the evaporation of the liquid in the bucket, dampening of the contents of the basket obviously injuriously affecting the same, and to further protect and guard the chemicals from dampness the basket is divided into the two chambers by the double transverse partition and the space between the walls of the partition communicates at its ends with openings 20a in the side walls 18 for the purpose of permitting the air to circulate through said space between the two chambers of the basket. For the same reason the lbottom 19 is preferably of hollow' construction in order to provide an air space which will aid in protecting the chemicals from dampness. By providing for a circulation of air the contents of the basket are kept perfectly dry and therefore in proper condition to respond with best effects when precipitated into the Water.

From the above description it will be apn parent that I have produced a fire extinguisher possessing the features of advantage enumerated as desirable and I wish it to be understood that I do not desire to be restricted to the exact details of construction shown and described as obvious modifications will suggest themselves to one skilled in the art.

Having thus described the invention what I claim as new and desire to secure by Letters Patent, is z 1. A bucket, a cover therefor having an opening, a cage bearing a hinged relation to said cover and normally closing the opening thereof, and a chemical basket carried and surrounded by said cage and provided with a movable bottom.

2. A bucket, a cover therefor having an opening, a cage bearing a hinged relation to said bucket, and a chemical basket carried and surrounded by said cage and provided with a movable bottom, means for holding the bottom closed, and means for disengaging the holding means for permitting the bottom to open and discharge the contents of the basket into the water.

3. A bucket, a cover therefor having an opening, a cage bearing a hinged relation to said bucket, and a chemical basket carried and surrounded by said cage and provided with a hinged bottom, means to hold the bottom normally closed and a push rod to disengage said means and permit the bottom to swing down.

4. The combination of a bucket, a cover therefor provided with an opening, a perforated cage rovided with ilanges at its lower end and hinged to said cover at the rear margin of said opening and adapted to close said opening normally, means to fasten said cage in fixed relation to the cover, a basket depending into the perforated cage and tapering downwardly and having its upper side closed, a bottom for the basket hinged to the same at one end, means forholding the bottom of the basket normally closed, land means for effecting the opening movement of said bottom.

In testimony whereof I aflix my signature, in the presence of two witnesses.

HENRY SIEBEN.
